DEVICE FOR JOINING THE ENDS 0F BELT-S.

Patented Feb. 26, 1918.

Application filed May 14, 1917. Serial No. 168,365.

1 b all whom it may concern:

Be it known that I, JAMns K. DIAMOND, a citizen of the United States, residing at Grand Rapids, in the county of Kent and tate of Michigan, have invented new and useful Improvements in Devices for Joining the Ends of Belts, of which the following is a specification.

The presentinvention relates to devices for joining the ends of a belt; and its object is generally, to provide an improved device 0 that character which shall be simple in construction and very eflicient in securely joining the belts ends; and more particularly, such a device all of whose par s shall lie within the surface planes of the belt to which it is applied; and further, to provide improved fastening means for securing the connecting members to the belt.

These and any other objects appearing hereinafter are attained by, and the invention finds preferable embodiment in, the device hereinafter described and illustrated by the accompanying drawings, in which:

Figure 1 is a view' in perspective of a gang of connecting members formed of a continuous wire; the position of the end of the belt towhich they are applied being shown in dotted lines;

Fig. 2 is a longitudinal section of the ends of a belt showing the manner in which such members are fastened thereto;

- Fig. 3 is a transverse section of a portion of the same taken on line 3-3 of Fig. 2;

Fig. t is a like sectional view taken on line 4-4 of Fig. 2;

Fig. 5 is an ed ewise view of the joined ends of a belt illustrating the manner of such joining;

Fig. 6 is a view in perspective of a fastener for securing the connecting member to the belt;

Fig. 7 is a like view of a modified construction of such a fastener;

Fig. 8 is a side view of the gang of connecting members before being applied to the end of the belt;

Fig. 9 is a side view of a single connecting member; and

Fig. 10 is a top view of the same.

The ends 1, 2 of the belt 3 are joined by means of connecting members 4 preferably formed of a continuous wire in gangs as shown in' Fig. 1. One set or gang of said members is securely fastened to one end of the belt and a corresponding set or gang to the other end of the belt, the projecting loop portions 5 of one set interlacing with the loop portions of the other seti a suitable pin 6 being inserted into the interlaced loop portions joins the ends of the belt together. In order that the belt may run smoothly over the pulleys the arms 7 of the connecting members are embedded in the belt as shown. The ends of the arms are provided with bights 8, which in the gang construction illustrated connect the plurality of connecting members together in spaced parallel relation, one bight in such construction being common to arms of adjacent connecting members. Suitable fasteners'9, 10 are driven into the belt over the bights, and are clenched by the turning over of their points, as shown, in order to securely anchor the connecting members to the belt. These fasteners may be'single-pronged as 9, or double-pronged as 10: In the latter case, their points are turned in opposite directions as illustrated in Fig. 3, to provide a more secure and more extended anchorage, such opposite turning being automatically effected by the opposite beveling of their points 14, 15, as shown in Fig. 7. The opposite sides 11, 12 of these fasteners con" verge toward their points, and in the drivenin position of the fasteners, said sides are parallel to the side edges of the belt: When the points of the double prongs are turned over oppositely and toward said edges of the belt they provide an anchorage less liable to pull out or to tear the belt than if these prongs were turned and clenched in a line in the lengthwise direction of the belt. The bights are turned inwardly '5. e.

the bights of the arms lying on one side of the belt are turned toward the bights of the arms on the other side of the belt, as illustrated. These bights (as well as the arms) are embedded in the belt deeply enough, as

by sufficient pressure, that the heads 16 of the fasteners when driven in over the bights are likewise thus embedded as shown, so that no parts of the device extend above or outside the surface planes of the belts sides.

Such embedding of the inwardly-turned It will i bej seeir thatfby" renson of -this inwardly new I "fords a more secure anchoragec for the con:

necting members than if such strain was en tnelyone way or the other; The ends of the wirem-aybe provided with spurs 13, as

shimvm adapted to be driven into thebelt.

'Ihe connecting members may be formed separately as-shown inFigs. 9 and L0, each arm 7hav1ngnt ts end an inwardly-turned .b1'ght8."' J
